Features:

Quad-Core Processing: Provides four independent execution cores in a single processor package. Four dedicated processing threadshelp operating systems and applications deliver additional performance, so end users can experience better
multitasking and multi-threaded performance across many types of applications and workloads.

Intel® Wide Dynamic Execution: Improves execution speed and efficiency, delivering more instructions per clock cycle. Each core can complete up to four full instructions simultaneously

Intel® Smart Memory Access: Optimizes the use of the data bandwidth from the memory subsystem to accelerate out-of-order execution.A prediction mechanism reduces the time in-flight instructions have to wait for data. Pre-fetch algorithms
move data from system memory into fast L2 cache in advance of execution. These functions keep the pipeline full, improving instruction throughput and performance. 45nm versions further improve this feature,with more efficient methods of loading and storing data in main memory.

Intel® Advanced Smart Cache: Dynamically allocates the shared L2 cache to each processor core based on workload. This efficient, dual-core-optimized implementation increases the probability that each core can access data from fast L2 cache, significantly reducing latency to frequently used data and improving performance.

Intel® Advanced DigitalMedia Boost: Accelerates the execution of Streaming SIMD Extension (SSE) instructions to significantly improve the performance on a broad range of multimedia and compute intensive applications. The 128-bit SSE instructions
are now issued at a throughput rate of one per clock cycle, effectively doubling their speed of execution on a per-clock basis over previous generation processors. 45nm versions include a new Super Shuffle Engine,which improves existing SSE instructions while enabling significant gains on the latest SSE4 instruction set. SSE4-optimized applications, such as video editing and encoding in high-definition resolution, will see additional performance improvements.

Intel® 64 Architecture: Allows the processor to access larger amounts of memory. With appropriate 64-bit hardware and software, platforms based on an Intel processor supporting Intel 64 architecture can allow the use of extended virtual
and physical memory.

Execute Disable Bit: Provides enhanced virus protection when deployed with a supported operating system and prevents the code from infecting the system. Memory can be marked as executable or non-executable, allowing the processor
to raise an error to the operating system if malicious code attempts to run in non-executable memory.

Better Acoustics:Intel Core 2 Extreme Quad-Core processors are equipped with a Digital Thermal Sensor (DTS) to enable more efficientprocessor and platform thermal control. Thermal sensors located within the processor measure the maximum temperature on the die at any given time. The acoustic benefit of temperature monitoring is that system fans spin only as fast as needed to cool the system and slower spinning fans generate less noise. This Intel-designed thermal solution for boxed processors utilizes a 4-pin header with variable fan speed control, based on processor temperature and power usage to minimize acoustic noise levels. The latest 45nm boxed Intel Core 2 processor includes a new, more advanced thermal solution with improved acoustic and thermal performance
